Patented Feb. 6, 1940 UNITED STATES PATENT OFFICE WOVEN FABRICS KosukeShiranezawa, Yonezawa-shi, Japan Application September 12, 1938, SerialNo. 229,630 2 Claims. (01. 139-420) This invention relates to wovenfabrics, and has for its object to provide a fabric for both ornamentaland practical uses, without presenting susbtantially a disagreeableluster, and without-substantially napping.

In the accompanying drawing:

Fig. 1 is an enlarged plan view of a piece of the fabric embodying theinvention to illustrate a manner of weaving.

Fig. 2 is an enlarged vertical sectional view of the fabric taken alongone pair of warp threads.

Referring more particularly to the drawing, I represents silk orartificial silk warp threads, and 2 represents hard twisted silk orartificial silk weft threads. A knitted hollow cord 4 is interwovenbetween alternate, or every two or more weft threads and is passed overa number of the warp threads I in suitable spaced relation, as indicatedat 5.- The fabric thus produced is sub- Jected to a scouring orfinishing operation.

On the scouring or finishing of the fabric, the hardtwisted weft threads3 considerably shrink or pucker, whereby the portions of the knittedhollow cords 4 passing over a number of the warp threads are squeezedand swelled out on the surface of the fabric, due to their being hollowand elastic to some extent, to form numerous small bud-like globules 5,which present a beautiful appearance as if numerous buds were scatteredover the surface of the fabric. This is the result of the use of theknitted hollow and elastic cords in combination with the hard twistedand shrinkable -weft threads. Finer and more graceful buds may beobtained by the use of knitted hollow cords of an artificial silkrelatively difficult to be dyed, such as celanese artificial silk, orits mixture with other artificial silk.

It will be understood that the warp threads and weft threads may be anydesired threads or yarns, and that various specific beautiful figuresmay be formed on the surface of the fabric in accordance witharrangement of the knitted hollow cords between the weft threads andpassing' over a number of the warp threads and further that one or moreadditional weft threads of any suitable material may be interwoven intothe fabric'in such a manner as to form a desired texture.

The fabric thus produced will be soft to the touch and will have lesstendency to crumple in comparison with ordinary artificial silk fabric,due to the softness and elasticity of the knitted hollow cords used, andis suitable for use in 10 making a handbag, necktie, purse, pocket-book,coat and overgown, because the fabric is relatively thick due to thesmall bud-like globules on the surface of the fabric, and isincidentally inexpensive to manufacture.

Having thus fully described the invention what is claimed as new anddesired to be secured by Letters Patent is:

1. A woven fabric comprising interwoven warp and weft threads, thethreads extending at least 20 in one direction being hard twisted andshrinkable, and knitted hollow cords extending parallel to the hardtwisted and shrinkable threads and engaging at suitable intervals atleast one of the threads which lie at substantially right angles 25thereto and passing over a number of said threads in suitably spacedrelation so as to provide a number of bud-like globules arrangedthroughout the surface of the fabric in any desired design when thefabric is subjected to a 30 scouring and finishing operation.

2. A woven fabric comprising interwoven warp and weft threads, the weftthreads being hard twisted and shrinkable, and knitted hollow cordsextending parallel to the weft threads and engaging at suitableintervals at least one of the warp threads and passing over a number ofsaid warp threads in suitable spaced relation so as to provide a numberof bud-like globules arranged throughout the surface of the fabric inany de- 0 sired design when the fabric is subjected to a scouring andfinishing operation.
